Note that this step takes a long time.
If you don't want to evaluate the pretrained models, you may skip to the next step and evaluate with our predictions under data/predictions.
./eval_scripts/baseline.sh <path/to/anserini> <path/to/index> <2, 5>
- Compute document score
Set the last argument to True if you want to tune the hyperparameters first. To use the default hyperparameters, set to False.
./eval_scripts/test.sh <qa_2cv, mb_2cv, qa_5cv, mb_5cv> <2, 5> <path/to/anserini> <True, False>
- Evaluate with trec_eval
./eval_scripts/eval.sh <bm25+rm3_2cv, qa_2cv, mb_2cv, bm25+rm3_5cv, qa_5cv, mb_5cv> <path/to/anserini> qrels.robust2004.txt
